Abstract
PURPOSE: To produce an engineering polyester component that has been highly polymerized and contains less carboxyl groops, by effecting powder molding of a saturated polyester mixed with bisoxazoline or bisoxazine.
CONSTITUTION: Powder of a polyester resin composition including 0.01 to 10 parts by weight of bisoxazine compounds or bisoxazolines of the general formula I (wherein n represents 0 or 1, D represents a bivalent organic groop, and X represents a bivalent organic groop capable of forming a five- or six-membered ring) and 100pts.wt. of saturated polyester is subjected to powder molding in a conventional manner. Since the compounds having the formula I is highly reactive with a carboxyl groop, the contents of end carboxyl groops in the polyester are significantly reduced, its resistance to moist heat is improved, and at the same time its molecular weight is significantly increased, that is, its mechanical strength is improved.
